Abstract

pH studies of palmito polyphenol oxidase are carried out with either 4-methylcatechol or pyrogallol as substrates. The pH profile is independent of the nature of the substrates tested. The symmetrical behaviour and the very slight differences between the values obtained suggest the existence of only one site on the molecule for o-diphenol substrates.

摘要

以4-甲基邻苯二酚或连苯三酚为底物，对棕榈多酚氧化酶进行了pH研究。pH曲线与所测试底物的性质无关。所获得的值之间的对称行为和非常细微的差异表明，分子上对于邻二酚底物仅存在一个位点。
